The present study was designed to explore whether sustained attention tasks can be
adequately described by a mindlessness perspective or a limited resource perspective. One …

Robertson, Manly, Andrade, Baddeley, and Yiend (1997) proposed that the decline in
performance efficiency over time in vigilance tasks (the vigilance decrement) is …

The vigilance decrement has been described as a slowing in reaction times or an increase
in error rates as an effect of time-on-task during tedious monitoring tasks. This decrement …

The resource view on vigilance performance was tested. First, a low demanding task was
compared with a similar low demanding task in which stimulus presentation was less …

The dominant theory amongst vigilance researchers is resource theory. From this theoretical
perspective the increase in lapses with time on task, the vigilance decrement, is due to the …

Decrements over time in sustained attention (vigilance decrement) have been attributed to
filtering, reduced tonic arousal, neural habituation, and related factors. A recent taxonomic …

It is well known that when human observers must monitor for rare but critical events,
probability of detection tends to wane over time, a phenomenon known as the “vigilance …

Results of empirical studies using computerized tests of sustained attention are summarized.
Factors that affect vigilance performance fall into three broad categories: task parameters …

In this report, we examined the impact of rest breaks and goal switches on the vigilance
decrement—the change in performance with time-on-task—and subjective stress and …

Two models of recently reported high workload associated with vigilance tasks are the direct-
cost and indirect-cost views. The former attributes high workload to the need for continuous …
